Be it known that I. lViLLL-mr lV. VA'rsoN, a citizen ol? the United States, residing` at the city ot Jamestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improveinents in Metal Window Screens for Rail- Vto be operable to withdraw: said bolts from the locking notches inthe guide strips on the window frame when in the raised position in the :traine of the car above the visible window traine, in which raised position said bolt cannot beinanually withdrawn,

4but must be actuated by means'of a withdrawal hoolr which draws the screen downward to `screen the window opening; `and the invention consists in the novel features and combinations hereinai'ter set lorth and elaiined. l

In the drawings, Figure lis an elevation of a car window with the car frame in section showing the improved window screen in the elevated position with the withdrawal hook in position for withdrawing the bolts from their locking engagement in the notches i'nthepguide strips, and ior drawing the window screen downward to screen the window opening when the sash is raised. Fig. 2 is a horizontal;crosswise sectional view at line 2--2 in Fig. S; and Fig. Sis a vertical sectional view'at line Beil-in Fig. 8, the central portions ot the traine being broken away to show large sectionalview oi the ,trarne sides. Fig. 11 is a perspective view ol; the-strengthened end ot the tape showing the opening therethrougl'l to receive the pivot pin. Fig; 5 is aperspective view oi the channel-shaped lever piece in the lower frame side as arranged for engagement by awithd 'awal hool. Figs. 6 and 7 show lengthwise sectional` and end elevations of the combination bolt barrel and pin guideway. Fig. S is an `elevation of the screen fra-ine, portions of the screen 'frame being shown in section toshow ythe construction and arrangement of the-same yaste the tubular trarne sides and the flexible tape and pulleyconneetion between the turn or crank plate in the upper traine side and the withdrawal lever in the lower iframe side oractuating said turn or cranlr plate to withdraw the locking bolts and lower the screen. Fig. 9 is a crosswise sectional view of the frame at line 9-9 iny Fig. 8 showing the preferred. constructionr of said trarne sides. Fig. 10 is a lengthwise sectional view of an upper corner ot thetubular `traine showing the spring bolt, link, turn plate, and tape and pulley connection for the withdrawal of the spring bolts and the openings in the frame side. F i`g "11 is', a sectional view` of one of the struck-up bolty barrels showing the spring 'bolt within the saine; and Fig. 12 is an end elevation oi the same.

F ig.` 13 is a perspective view of the insert strip torV holding the lateral side springs in working position within the frame side.

Like characters ol' reference refer to correspondingparts in the several views.

The numeral` 15 designates the tubular sheet `metal ranie sidexwhich is ont and bentfroin the flat sheet inf-tal` strip bv means oli suitabledies so as to form the lengthwise groove 16 along vthe inner frame side. f,

The numeral 17 designates the upper iranie side or toprail which is preferably formed of one or more strips et sheet metal shaped so as to provide said lengthwise -lgroove 16 which opens sidewise along the inner edge, and theA narrow lengthwise groove 184 which alsoopens sidewise"alongv the outer edge, both oji said grooves enlargingA inwardly. `The inner groove 16 enlarges inwardliv to receive the spline for holding strip 19 ior att-aching the screen 'fabric 2O within the groove 1G. The'outer groove 18 enlarges inwardly to receive and retain therein the weather stripping 21 'which rits within the ygroove and entends beyond the plane ot'fthe" `ail or 'frame side.

The top rail or upper tubular trarne side 17 is preferably formed of a plurality oi sheetv metal strips, the .contacting edge Lportions of which are pressed'together and bent into the lengthwise-channel ygrooves 16 and 18 along the inner and outeredges of the saine, the edges of said; strips being so arranged as to narrow the mouths of each of said grooves 16 and 18, the thickness of the edges oi' said inturned sheet inetel e hold the splineV 779 andthe weather stripping 2l. The eontltrting edges ot seid sheet inetel stripsV are preteribly wenn-fd or Aeeldered or otherwise attached so that they rannot `turn or wezifve upon one` another,`

thereby giving rigidity te the flirtline.

The channel-shaped' lever "piece 62- which fig-@Oasen Y wt isengaged bv the'lowering hook` 26 serves also to draw thescreen Ytra-meV downward until itcan lbe `manuallv :grasped and lowered, therebyserving a double purpose to Withdraw the bolts QQand 30 and to lower fthe screen trame. The channeleshaped leverpiece (52 is pivotallv attached in `the lower corner at 6B, while the tape-59 isipivotally attached at 64 at the upper corner. As stated. the lever ypiece't `is pivotally attached over the slotted opening 65 inthe under edge of thelower rameiside and has ythe slotted opening 665therein for the insertion of the lowering` hook 2G over-a cross 'bar 67' as shown in Figs,` Sand Si, so that said lever piece GQvmav be drawn downwardas shown in dotted ,outline in lowering' the screenv frame `as hereinbetore described. soon as the loweringhook is removedvand the spiingboltsQQ and 30 are `permitted to spring' outward into the `lower locking notches in the guide strips on the window trame. said lever piece 62 will be drawn upward into the closed position in the lower frame side.

1When the screen trame is in the lowered ou accessible position, it is lnecessarv to manually actuate the spring` locking bolts 29 and 30. For this purpose the manual actuatinglevers and 5G are provided which extend down through the lower edges of thel upper frame side. and are connected to said spring boltsv and 20. their actuating! links being` pivotallv attached within said upper 'Frame side. ln order also to assemble the spring bolts. turn plate and connective link mechanism with the manual actua-tingr levers and tape within the upper tramevside 17. a cover 69 is provided i'or said frame side 17 which fits closely over the same as shown in Figs. 3 and l0. This arrangement permits the provision of openings 70, 7l and 72 in said top rail 17 opposite the points of assemblanne ot' said parts. The cover 69 is channel-shaped and fits closel)7 over said top rail 17 so it can be sprungT onto the same and give a pleasing finish. vet permits its Quick removal for access to the connective joints to assemble or repair the same.

The cover (i9 is shown in Fig. l, with the locking mechanism in dotted outline within the (op rail beneath said cover. laid cover GS) is not shown in Fig. 8 since said top rail is in section, the side upon which said cover @D would be placed. being removed. The exact channel shape and the relation ol said cover in fitting` over the parts is ele-arbT shown in Fig. in cross section.

The channel strip insert 38 is held within lthe frame side and against displacement by means of a screw 'T3 and a closed end Tel on the lower end of said channel strip insert 38.
